1. About the main points of the invention The main points of the medical simulation apparatus 100 of the present invention will be described with reference to FIG. In this embodiment, a case will be described in which an operator (such as a dentist) acquires the horizontal medical technique using the medical simulation apparatus 100.

  Here, “horizontal medical care” is different from the conventional medical care that the surgeon looks into the patient's oral cavity, and as shown in FIGS. Is performed without looking into the patient, that is, without destroying the posture of the operator D. FIG. 2A is a top view showing a state where the patient K is receiving horizontal medical care, and FIG. 2B is a side view showing a state where the patient K is receiving horizontal medical care.

  Employing horizontal medical care not only reduces the burden on the operator who has to concentrate precise work for a long time, but also reduces the onset of diseases such as lung cancer with dust. However, since it takes time to acquire the horizontal medical technique because it is necessary to perform medical care with the same posture, it is particularly effective to use the medical simulation apparatus 100 of the present invention.

  As shown in FIG. 1, a medical simulation apparatus 100 according to the present invention includes an oral model 4 that is an oral model having one or more pseudo teeth 2 and a medical instrument for performing a simulation of medical practice on the pseudo teeth 2. And a tablet PC 10 which is a portable computer having a display 8 which is a display means. The medical simulation apparatus 100 of the present invention is placed on a general table 14.

  Each medical guidance data corresponding to a combination of a tooth and a tooth surface at a specific position is stored in advance in a storage unit (described later) included in the tablet PC 10. For example, corresponding to the combination of the specific position “front right upper jaw” and its tooth surface “cheek”, (i) the operator's direction, (ii) the maxillary occlusal surface, (iii) the patient's head Image data, moving image data, and the like indicating appropriate medical practice such as side rotation and (iv) how to hold the turbine 6 are stored.

  When the operator sitting on the chair 12 holds the turbine 6 and approaches or contacts the pseudo tooth 2 at a specific position, the sensor S of the pseudo tooth 2 detects this. In the tablet PC 10 connected to the sensor S, a combination of a tooth and a tooth surface at a specific position to be subjected to a simulation of a medical practice is determined. For example, the combination “11B” of the tooth code “11” indicating the specific position “frontmost tooth of the right upper jaw” and the tooth surface code “B” indicating the tooth surface “cheek side” is determined. Here, not only the position of the tooth but also the tooth surface is determined because there are a plurality of different medical guidance data for one tooth.

  Further, medical guidance data corresponding to the determined combination of teeth and tooth surfaces at a specific position is extracted from the storage unit and displayed on the display 8 of the tablet PC 10.

  A display example of the display 8 is shown in FIGS. For example, before a combination of a tooth and a tooth surface at a specific position is determined, a medical care guide application as illustrated in FIG. 3A is activated, and the display 8 of the tablet PC 10 displays “a tooth and a tooth surface for performing a medical simulation. Please select by placing the turbine on the teeth. ”Is displayed. Furthermore, after the combination of the tooth and the tooth surface at the specific position is determined, as shown in FIG. 3B, an image showing an appropriate medical practice is displayed by the medical care guide application.

  Specifically, in the display example shown in FIG. 3B, (i) the operator's direction “12 o'clock”, (ii) the maxillary occlusal surface “−7 °, one lateral finger”, and (iii) the patient The side rotation of the head “right 12 °” and (iv) how to hold the turbine 6 “grip 2 (angle of finger contact portion and instrument)” are displayed as appropriate medical treatments.

  As a result, the surgeon can cut the pseudo tooth 2 by the turbine 6 in an appropriate manner on the tooth surface of the tooth to be subjected to the medical practice according to the medical care guide displayed on the display 8 of the tablet PC 10. It is possible to learn efficient medical practice.

  In particular, in horizontal medical care, as shown in FIGS. 2A and 2B, since the operator D does not look into the oral cavity of the patient K during medical care, various restrictions such as how to hold the turbine 6 occur. Although the difficulty in acquiring the technology is a problem, the use of the medical simulation device 100 of the present invention makes it possible to acquire the horizontal medical technology in a short period of time.

2. Configuration of medical simulation apparatus 100 The configuration of the medical simulation apparatus 100 shown in FIG. 1 will be described with reference to FIG.

3. First Embodiment [Hardware Configuration of Tablet PC 10]
First, the hardware configuration of the tablet PC 10 (FIG. 1) will be described with reference to FIG.

  As illustrated in FIG. 8A, the tablet PC 10 includes a CPU 110, a memory 112 as a storage unit, a touch sensor 114, a display 116, a speaker 118, and an I / O 120.

The memory 112 provides a work area for the CPU 110. In addition to the operating system (OS), the memory 112 stores a medical guide program 130 and a medical guidance DB 132.
FIG. 9 shows a data example of the medical guidance DB 132. As shown in FIG. 9, each medical guidance data corresponding to a combination of a tooth code and a tooth surface code (data indicating a medical practice for each medical element item “operator direction”, “maxillary occlusal surface”, etc.) is an image. It is stored as data.

  The touch sensor 114 detects a position where the user touches the display 116 and receives a command corresponding to the position. The display 116 displays images such as a medical guide and a user interface. The speaker 118 outputs sound such as a warning sound to the outside.

  A wiring from a pressure sensor S provided so as to contact the bottom of each pseudo tooth 2 is connected to the I / O 120 which is a data input / output port so that contact with the pseudo tooth 2 can be sensed. FIG. 8b shows the structure of the oral cavity model 4 (FIG. 1).

  As shown in FIG. 8b, the oral cavity model 4 includes an oral body 4a that is shaped to imitate a human oral cavity part and an oral cover 4b (illustrated by a dotted line) that is shaped to mimic the head. . Note that the oral cavity model 4 is configured such that a lateral rotation operation M1 and an adjustment operation M2 of the maxillary occlusal surface (an angle with the floor and an opening degree) are possible.

  A hole is provided at a predetermined position of the oral body 4a, and the pseudo tooth 2 is fitted into the hole, and a pressure sensor S is provided at the bottom of the hole. The wiring of the pressure sensor S is drawn out of the oral cavity body 4a and connected to the I / O 120 (FIG. 8a). The oral cavity cover 4b has a hole in a portion corresponding to the mouth and is disposed so as not to cover the opening of the oral cavity body 4a. The pseudo teeth 2, the oral cavity body 4a, and the oral cavity cover 4b can be formed of a material such as plastic.

[Flowchart of processing by the medical care guide program 130]
Processing executed by the medical care guide program 130 (FIG. 8a) will be described with reference to FIG. FIG. 10 is a flowchart showing processing executed by the medical care guide program 130.

  When an operator having the turbine 6 contacts any pseudo tooth 2, an input signal from the pressure sensor S is input to the tablet PC 10 via the I / O 122.

  When the CPU 110 receives an input from the pressure sensor S (Yes in step S10), the CPU 110 determines a tooth code at a specific position to be subjected to a medical simulation (step S12). In addition, since the pressure sensor S is provided in each pseudo tooth 2, by determining which pressure sensor S is the input, it is possible to specify which position the tooth is.

  FIG. 11 is a diagram showing a general tooth arrangement. Each pseudo tooth has a number indicating a specific position (in the case of the FDI method, as shown in FIG. 11, the upper right upper jaw is “11 to 18”, the upper left upper is “21 to 28”, and the lower right lower is “31”. ˜38 ”, and the lower left lower jaw are“ 41 to 48 ”), which are used as tooth codes. In addition, even in different teeth, the same medical treatment contents are grouped.

  Next, CPU110 turns on a timer (step S14), and transfers to a tooth surface selection mode. FIG. 12A is a diagram showing names of tooth surfaces. In the tooth surface selection mode, the operator performs an occlusal surface O (Occulusal surface), a buccal surface B (Buccal surface), a lingual surface L (Lingual surface), a mesial surface M (Mesial surface), and a distal surface as shown in FIG. A predetermined tooth surface composed of D (Distal surface) and gingiva G (Gingiva) is selected. This is because even if the teeth are the same, appropriate medical practice varies depending on the type of tooth surface.

  If it is determined that the input from the pressure sensor S has been received within the predetermined time T1 (Yes in step S16), the timer is turned on again (step S18), and the input from the pressure sensor S is awaited. If it is determined that the input from the pressure sensor S has been received within the predetermined time T2 (Yes in step S20), the selectable tooth surface candidates that have received the input are switched to the display 116 and displayed in order (step S22). For example, as shown in FIG. 12B, selectable tooth surface candidates are highlighted in order (hatched portion in FIG. 12B).

  Each time the CPU 110 receives an input in step S20, the timer is turned on (step S24), and it is determined whether or not a predetermined time t3 has elapsed since the last input (step S26). A tooth surface candidate when a predetermined time t3 has elapsed from the last input is determined as a tooth surface to be simulated (step S28). For example, the buccal side surface B and the centrifugal surface D shown in FIG. 12 are determined.

  Finally, the CPU 110 refers to the medical guidance DB 132 based on the combination of the tooth code at the specific position determined in S12 and the tooth surface code determined in S26, and extracts corresponding medical guidance data (step S30). ). Further, the extracted medical guidance data is displayed on the display 6 (step S32). Thereby, for example, medical guidance data as shown in FIG. 13 is displayed, and the surgeon can execute an appropriate medical practice with reference to this.

4). In the second embodiment, the medical guidance data is displayed when the simulation is executed. However, as shown below, the medical guidance data indicates whether the surgeon is performing an appropriate medical practice. You may make it evaluate based on.

  FIG. 14 shows a hardware configuration of the tablet PC 10 '. The memory 112 stores a medical evaluation program 140, a medical guidance DB 132, and a medical evaluation DB 142. The data stored in the medical guidance DB 132 is the same as that shown in FIG.

  In FIG. 19A-D, the connection part of each evaluation sensor E1-E6 is shown.

  As shown in FIG. 19A, the first evaluation sensor E1 is provided at the connecting portion of the chair 12 'and detects "the direction of the operator". The chair 12 ′ shown in FIG. 19A is attached to the angle display plate 24 so as to be rotatable.

  As shown in FIG. 19A, the second evaluation sensor E2 and the third evaluation sensor E3 are provided on the lateral and vertical rotation axes of the oral model 4, respectively. "Side rotation" is detected.

  As shown in FIG. 19B, the fourth evaluation sensor E4 is configured by attaching a pressure sensor to the turbine 6. The patient can detect the portion having the turbine 6 and determine which type of “how to hold the turbine” is.

  As shown in FIG. 19C, the fifth evaluation sensor E5 is configured by disposing a pressure sensor on a finger sack attached to the operator's finger. By detecting the position of the finger touching the tooth, the position of the “finger rest” can be determined.

  As shown in FIG. 19D, the sixth evaluation sensor E6 is configured by a small camera that captures an image in the line of sight of the operator. By analyzing the image in which the tooth surface is reflected on the mirror, it is possible to determine which type of “sight line direction” is.

  FIG. 15 is a diagram illustrating an example of data in the medical evaluation DB 142. As shown in FIG. 15, the medical treatment evaluation DB 142 stores medical guidance data for each item as data in text format, and is compared with execution data to determine whether or not an appropriate medical practice is performed.

  FIG. 16 is a flowchart showing processing executed by the medical evaluation program 140. The processing from step S10 to step S30 is the same as the flowchart shown in FIG.

  After step S30, the CPU 110 displays the start of evaluation as shown in FIG. 17A and shifts to the evaluation mode (step S34). Further, the medical treatment element item to be evaluated is displayed on the display (step S46). For example, a display indicating that “the direction of the operator” is being evaluated is performed.

  When the CPU 110 receives an input from the evaluation sensor En (for example, the evaluation sensor E1 shown in FIG. 19A) corresponding to the medical element item (Yes in step S48), the CPU 110 sends the execution data of the acquired medical element item to the corresponding item. Each is compared with medical guidance data (step S50).

  As a result, when the execution data of the acquired item does not match the medical guidance data of the corresponding item (No in step S52), a warning sound is output from the speaker 118 (FIG. 14), and the medical guidance data of the mismatched item is output. This is displayed on the display 116 (step S54). Thereafter, the next medical element item is displayed on the display (step S46), and then the process returns to step S48 to resume the evaluation of the medical practice.

  The surgeon executes the medical practice again and receives evaluation with reference to an appropriate medical practice as shown in FIG.

  When the acquired execution data of the medical element item matches the medical guidance data of the corresponding item (Yes in step S52), the correct answer sound is output from the speaker 118 (FIG. 14), and the completion flag “ 1 "is stored (step S56).

  Until a completion flag “1” is stored in all clinical criteria items, a predetermined order (eg, item (i) operator direction, (ii) maxillary occlusal surface, (iii) lateral rotation of the patient's head) ( The evaluation process is performed in the order of iv) how to hold the turbine 6, (v) finger rest, and (vi) the direction of the line of sight) (No in step S58). After the completion flag “1” is stored in all the clinical criteria items (Yes in step S58), the evaluation of the diagnostic method is terminated.

  In the above embodiment, the medical practice is evaluated for each medical element item. However, as shown below, all the medical element items may be evaluated at a time.

  FIG. 18 is a flowchart showing the processing executed by the medical care evaluation program 140 'that evaluates all the medical element items at once. Note that the processing from step S10 to step S34 is the same as the flowchart shown in FIG.

  After step S30, the CPU 110 displays the start of evaluation as shown in FIG. 17A and shifts to the evaluation mode (step S34). In the evaluation mode, when input from all the evaluation sensors E (E1 to E6 shown in FIG. 19) is received (Yes in step S36), the acquired execution data of each item is used as the medical guidance data of the corresponding medical element item. Each is compared (step S38).

  As a result, if any of the acquired item execution data does not match the medical guidance data of the corresponding medical element item (No in step S40), a warning sound is output from the speaker 118 (FIG. 14), and the items that do not match The medical guidance data is displayed on the display 116 (step S42, FIG. 17B). Then, it returns to step S36 and restarts evaluation of medical practice. The surgeon performs the medical practice again for evaluation with reference to the appropriate medical practice shown in FIG.

  When the execution data of the acquired item matches all the medical guidance data of the corresponding item (Yes in step S40), the correct answer sound is output from the speaker 118 (FIG. 14) (step S44), and the evaluation of the diagnosis method is completed. To do.

5. Other Embodiments In the above embodiment, an image showing medical guidance data is displayed by the medical guidance application (FIG. 3B). However, as medical guidance data, moving images, sounds, and the like are displayed and output. May be.

  In the above embodiment, the tablet PC 10 is used as a portable computer having the display 8 serving as a display means. However, other devices (such as a desktop PC and a notebook PC connected to the display device) may be used.

  In the above-described embodiment, it is determined that the turbine 6 (high speed handpiece 32) has contacted the pseudo teeth 6. However, the turbine 6 (high speed handpiece 32) has approached the pseudo teeth 6. You may make it detect. For example, a coil is embedded in pseudo teeth, and it is detected that electricity has flowed through the coil when the turbine 6 approaches.

  In the above embodiment, the tooth surface is selected after the pseudo tooth at the specific position is determined. However, the pseudo tooth and the tooth surface at the specific position may be determined at the same time. For example, a conductive metal may be coated for each tooth surface of the pseudo tooth at a specific position, and energization due to contact with the turbine 6 may be detected.

  In the above embodiment, the sensor S is provided on the pseudo tooth 2, but the sensor S may be provided on the turbine 6 or other than that.

  In the above embodiment, (i) the operator's direction, (ii) the maxillary occlusal surface, (iii) the lateral rotation of the patient's head, (iv) how to hold the turbine 6 are displayed as medical guidance data. However, at least how the turbine 6 is held may be displayed as medical guidance data.

  In the above embodiment, as a result of comparing the execution data of the acquired item with the medical guidance data of the corresponding item (No in step S40 shown in FIG. 18), the medical guidance data is displayed on the display 116 for items that do not match. However, it is also possible to calculate points for matching items and display them together or alone.
